This places the icons where I want them to be (I decided I'm happy with them all in a line instead of in a grid) but I know this isn't the best way to do this, because now I can't enter anything into my "post nav" section. It won't show up.

This would be so much easier if I had a index.html file to work with...when I open the page in Chrome's dev tools, it shows a html doc that I wish I could access. Please explain this to me.
